Question

How do you solve `2(3x+4)-3=5+6x`?

Answer 1

`x` can have have value.

Explanation:

Multiply out he bracket first

`2(3x+4)-3 = 5+6x`

`6x+8-3 = 5+6x`

`6x+5 = 6x+5" "larr` notice the two sides are identical

`6x-6x = 5-5`

`0=0`

This is a true statement, but there is no `x` left to solve for.
This is an indication that you are working with an identity which means it is an equation which will be true for any value of `x`.

There are infinitely many solutions.
